Letters Patent No. 76,930, dated April 21, 1868.

IMPROVED FRAME roe WINDOW-screens.

Be it known that I, CHARLES F Lmsco'r'r, of Woburn, in the county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in-Fram es for Window-Screens, &c., of which the following is a full,'clear, and exact description, reforencc'being had to the accompanying drawings, making apart of this specification, in which i Figure 1 represents a frame embodying my invention.

Figure 2 is a section of one of the sides of the frame. 7

Figure 3 is a view of my device for connecting the frames together.

Figures 4 to17 are details, showing the device in the different stages of manufacture.

Figure 8 shows a. modification of my device made of cast steel.

The object of my invention is to produce a simple, cheap, and useful means for securing together the ends of a frame, which is designed to be used more particularly for window-screens, though it may be appliedtto picture and other frames, and the invention consists in the employment of thin metal clasps, which are made to fit over the inner edges of a frame at the corners, orwherc the sides are joined together, in such a manner that the sides may be readily slipped into the said clasps where they will be firmly held, and form a strong frame.

Referring to the drawings, fig. 1 represents a frame for a window-screen, the sides, A, of which are held together by the clasp B on the inner corner of the frame. The sides of the frameA are formed oi strips ofwood moulded alike on both sides, as shown in section in fig. 2, so that in case of any unevenness in any of the sides they may be turned and fitted to the clasps on the opposite sides if necessary groove or-recess is made in one side of each of the pieces of the frame, in which is fitted a tongue, a, for the purpose of securing the-screen to the frame in a well-known manner;

B represents the clasps of the' form when finished, shown-in figL3, and fitted in each inner corner of the frame. It is composed of a piece of tin or sheet metal, as follows A square piece of tin or sheet metal, of about the size and shape, as shown in fig. 5, is cut out, and a short slit is made in the centre on each side. It is then placed on a former, and the sides are curved over, as shown in figs. 3 and 4; it is then bent at right angles, and a brace, e, fig. 7, formed from a plate, fig. 6, is soldered to the underside of the bent piece 13, which renders it very'firm and stiff. The clasps are then fitted over the edges of the sides A, and the whole frame is thus firmly secured p The claspthen formed takes but very little material, is very easily made, and very readily adapted to the sides of the frame. It may be applied equally well to picture and other frames.

Instead of being made of sheet metal, the clasp may be cast in one piece of'light metal, with the corners of the same meeting, so as to form a mitre, as shown in fig. 8. v

I am aware that frames have been connected together at their corners on the outside of the frame, but these are objectionable in many respects, and I do not claim such device, but

What I claim, and desire to secure by Letters Patent, is-

The clasp B, made of sheet or cast metal, and attached to the innoiycorner of a frame, for the purpose of.

securing the sides of the frame together, substantially as set forth.

In testimony whereof, I have signed my name to this specification in the prcscnceof two subscribing witnesses.v
